While in the transient world...
While in the transient world, they had veils over their sight which blocked their vision and thus, did not submit to the Truth. However in the next life, the affair shall be clear and easy to see that just as the brothers of Yusuf (as) were forced to concede, the disbelievers too shall have to concede to the reality of Allah (SwT)!
In summary, on the Day of Resurrection, Allah (SwT) will be manifest everywhere and thus, one of the reasons why the Day of Resurrection is referred to as “يوم لقاء الله” or “The Day of Meeting Allah” is that on that Day, the effects of His greatness will be manifest such that there shall be no room for error in comprehending Him! In addition, this phrase “لقاء الله” means that each person shall see himself in the presence of Allah (SwT).
This point is very important to keep in mind since the worst form of punishment for the servants on that Day shall be the state of embarrassment which they will feel due to their despicable actions.
It is this embarrassment that will actually burn them more than the fire of hell since that Day is also known as “يوم تبلـى السرائر” or “The Day when all of the actions of all individuals will be plain and manifest to see (for everyone).” The Prophet (S) has thus told us that, “On that Day, if a person was to be one who does not possesses three characteristics, then he has truly given up a great capital.” The first part of the tradition reads: “…the person who comes to Allah with that which Allah had made obligatory upon him will be of the most worshipping of people…” It is amazing to see people run after the recommended actions (mustahabat), however they leave aside the obligatory actions (wajibat) and such people are numerous in number!
For example, they will stay up until the middle of the night beating their chests in mourning (‘Azadari) or will spend the night in recommended worship and studying, however when the time for Salatul Fajr comes, they are fast asleep and thus, end up missing their Salat! It is important to mention that we must know that not a single person - whether in the life of this world or the next life - shall ever be successful, except if he wakes up in the morning (for his Salat).
Everyone whom I have seen who has been a victorious in life has been so due to his waking in the morning for the prayers.
